Carbon modified transition metal oxides/hydroxides nanoarrays toward high-performance flexible all-solid-state supercapacitors

Well-aligned hierarchical carbon modified transition metal oxides/hydroxides NRAs have been successfully fabricated by using epitaxial growth of ZIF-8 as carbon precursor. Benefiting from the specific core-shell heterostructure and the conductivity of carbon layer, both ZnO@C@CoNi-LDH and Fe2O3@C NRAs electrodes exhibited excellent electrochemical performance. Based on this sophisticated nanostructure, a high-performed flexible solid-state supercapacitor (FSSC) was further successfully constructed.122
